    Sammanfattning : There is an increasing trend in manufacturing industry for producing complex and delicate parts. As a result, the importance of having a deeper understanding of machine systems, in order toget higher accuracy of machined parts, arises. This leads to an increasing demand of testingmachine accuracy under operational condition. LÄS MER

  4. 3. Numerical Assessment of Defects Effect on Boltless Composites Longitudinal Joints

    Master-uppsats, KTH/Lättkonstruktioner

    Författare :Mara Santaniello; [2020]
    Nyckelord :;

    Sammanfattning : The work presented in this thesis focuses on the numerical assessment of defects effect on potential boltless design for fuselage panels longitudinal joints, typically identified as High Load Transfer (HLT) configuration.

    Sammanfattning : A large amount of low-rise unreinforced masonry structures (URM) can be found in Groningen, the Netherlands. More and more induced earthquakes with short duration have been detected in this region due to gas exploitation. LÄS MER

  7. 5. Multilayered Lamination for Acoustic Board Manufacturing

    Master-uppsats, Lunds universitet/Innovation

    Författare :Angelica Madeland; [2019]
    Nyckelord :Acoustic panels; lamination techniques; sound absorption; insulation; Technology and Engineering;

    Sammanfattning : Saint-Gobain Ecophon manufactures acoustic ceiling tiles made primarily of glass wool and are interested in exploring the idea of a new manufacturing technique – using thinner layers of material and laminating these together. The possible benefits are, amongst others, the ability to use different kinds of material where they are the most useful, reduced costs, larger amounts of recycled material, less material waste, and more customizability.
